Imperial Veronica

#6640ba
Notes

Imperial Veronica (#6640BA) is a true indigo with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (259°, 49%, 49%) places it in the balanced band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. For a confident two-color system, pair it with its complementary lime. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Imperial
adjective

From the Latin imperialis, of the empire — applied to color since the medieval period for the hues reserved for sovereigns and empires: imperial purple of Tyrian dye, imperial yellow of Ming-dynasty porcelain. As a modifier, imperial implies saturation combined with the institutional weight of a color owned by a court. Sits in the bold-and-deep corner, alongside royal.

Veronica
noun

The genus Veronica, the speedwells — named for Saint Veronica, who reportedly wiped Christ's face on the road to Calvary. The cultivated V. spicata sends up tall blue-violet flower spikes in summer borders. The color refers to a fresh veronica spike: a saturated, slightly violet-shifted blue with the matte finish of small densely packed flowers. Cooler than lavender, warmer than larkspur, with the cottage-garden association of a hardy perennial.

Display P3 representation

The CSS Color 4 wide-gamut form of this color. Both swatches render the same color on every display — the P3 form only diverges from sRGB when a designer pushes channels outside sRGB's reach.

This color is chromatic enough that authoring it as P3 native (instead of clamping to sRGB) gives a perceptibly more saturated render on wide-gamut displays — modern Macs, iPhones, iPads, and most recent OLED laptops.
